clang-16 compiler complains with following error message in multiple
places:
error: incompatible function pointer types passing 'int (struct dirent *)' to
parameter of type 'int (*)(const struct dirent *)' [-Wincompatible-function-pointer-types]
error: incompatible function pointer types passing
'int (const void *, const void *)' to parameter of type 'int (*)(const struct dirent **, const struct dirent **)' [-Wincompatible-function-pointer-types]
This patch fixes all those places by correcting function pointer types
for scandir callbacks.
